2) The nick name of a sorority called Kappa Kappa Gamma, usually full of pretty but slutty girls. (Not all "kappas" are pretty... some are ugly but have big boobs). Kappa was supposed to be a sorority for very classy women, but unfortunately they are more trashy now than classy.
1) What comes after Iota? Kappa.
2) She thinks Kappas are the best things ever... too bad they're slutty.
